Cognition is the AI lab behind Devin, marketed as an autonomous AI software engineer that can take a coding task from prompt to written, tested, and deployed code with limited human input. Founded in late 2023 by Scott Wu, Steven Hao, and Walden Yan, the company also owns Windsurf, the AI-native code editor it acquired in July 2025. After a $1 billion raise in May 2026 it reached a roughly $26 billion post-money valuation, up sharply from about $10.2 billion in September 2025, on the back of fast-growing Devin enterprise revenue.

What They Do
Cognition builds autonomous coding agents. Devin is positioned not as an autocomplete or an in-editor assistant but as an agent that owns a task end to end: planning, writing code, running tests, debugging, and deploying, with a human reviewing rather than typing. That framing, an AI software engineer rather than a copilot, is the company’s distinct bet.
The 2025 acquisition of Windsurf added an AI-native code editor and a large developer user base, giving Cognition both an autonomous-agent product (Devin) and an interactive editor (Windsurf). The company also notes that the large majority of its own code is now written by its AI, which it uses as evidence of Devin’s capability.
Current Flagship Products
- Devin: An autonomous AI software engineer that handles coding tasks from planning through deployment, aimed at enterprise engineering teams.
- Windsurf: The AI-native code editor Cognition acquired in 2025, covering the interactive, in-editor coding workflow.
Strategic Position
Cognition’s moat is its lead on fully autonomous coding plus the distribution and editor surface it gained with Windsurf, letting it serve both the agentic and interactive ends of AI development. Its challenge is a crowded, fast-moving field: Cursor, GitHub Copilot, Claude Code, and others compete hard on AI coding, and autonomous agents still need careful human review for reliability. The very high valuation also sets a high bar for execution.
For AIpedia readers, Cognition matters as the company pushing hardest on the autonomous-software-engineer thesis. Devin suits teams comfortable delegating whole tasks to an agent with oversight, while Windsurf serves developers who want an AI-native editor.
